    2. Molting of the insect cuticle

    The molting process begins when cuticular epidermal cells are stimulated by exposure to 20-hydroxyecdysone – the insect molting hormone. The hormone enters the epidermal cells where it stimulates genes related to molting and the formation of new cuticle. The activated epidermal cells undergo mitosis or grow by cellular enlargement. This is the period of growth to form a new, larger cuticle for the next instar. The existing structural cuticle separates from the epidermal cells. This is termed apolysis. The resulting ecdysial space between the endocuticle and the epidermal cells is filled with a gel that contains inactive chitinase and protease enzymes. A new outer epicuticle layer of cuticulin is secreted.…

What we do is we take our cuticle nipper, and basically what we are going to do is any dead skin that has been pushed up from the cuticle pusher… and use our nipper and just gently clip it off. You don’t need to get too deep or don’t need to push any harder; we just need to get whatever excess there is.

    Pedicure Equipment, tools and Techniques : Pushing Back the Cuticles: How to Give a Pedicure

    Hi! My name is Anneka on behalf of expertvillage.com, and in this clip I’ll be showing you how to push back the cuticles.

I’m putting her back in the water so that way it will help soften it up for me when I do start to work on them. We are going to use our cuticle pusher and gently push back the dead skin around the nail and we would do the same on the other foot.
